A Shitty Job but someone needs to do it.

 

New Zealand's main cities pump out approximately 5,181,270 metric Tonnes of faecal matter (and loo paper) a year. Are our waste treatment plants coping?

The other heavy user (but not measured) are household Grey Water, with Showers, Baths, Dishwashers, Dishes and other chemicals used to keep thing clean and tidy?  What is the proliferation of these subjects and how it impacts with biological breakdown of our sewage plants and subsequent impact on the breaking down process in those plants.
